Folks it's about time to mention once again a very, VERY important topic with regards to motorcycle safety: Make sure your luggage is strapped or locked to your motorcycle in a way that it can't accidentally fall out of place!
Although I didn't actually witness the moment of the crash, I took the photo to the above showing how the bag looked jammed up in the rear of the bike and would estimate that nobody could have recovered from such a surprising jolt like that. It happened at about a 50mph on a right hand sweeping turn, and again, I don't think there's a motorcycle rider in the world that could have handled this without crashing. That point alone is reinforces why we all need to pay attention to this subject.
This "loose luggage" situation actually happened to me before once too, back in 2010 when I was out scouting what would become one of the motorcycle trip packages in Peru that we offer. You can see in the picture below how I actually had a cable lock combined with my tie-down straps when this took place. This combination of strapping and cables wasn't enough to keep my luggage in place though, and at about 65mph on a windy stretch of highway on the way to Cusco, my bags also slid down and got caught up in my KTM's rear wheel, locking it instantly.
Fortunately for me, my incident happened on a straight section of road and there weren't any other vehicles within eyesight. I was able to keep the bike upright, and the only "losses" I sustained were my destroyed luggage and clothes, and the almost fist-sized hole in my rear tire as shown below.
My 2 errors in the above scenario were that:
1) My luggage straps clearly weren't tight enough. As it turned out, I had weakened my strap-tightening hand the day before in a situation where I had to lay my bike down and avoid a serious encounter with an unseen guard gate. My right forearm was badly bruised and swollen, so only after this happened did I realize that my weak hand clearly didn't pull the straps tight enough that morning. (Yes, stupid of me, I probably shouldn't have been riding either.)
2) I was merely using that cable lock you see as a "lock" and not routing the cable in such a way that it would tightly secure the bags to the bike. If you're using a cable lock as I still do most of the time, it should at least be routed in a way that it also tightens your luggage to the motorcycle!
I had the right equipment, I just didn't use it effectively. That being said, let's spell it out clearly:
Back to the situation referred to in this video though, a small group of us had rolled up on the 2 riders and were there to help until the ambulance came. Despite being very badly beaten up from their crash, it appeared that they would be okay, although in quite a bit of pain for a while with broken ribs, and other possible problems. I never got their full names, but wish them the best in recovery from this incident.
I think we all wish this had never happened in the first place, and so this remains my primary message and wishes to you: Take your luggage situation seriously, think about how you're positioning and securing bags and attachments to your motorcycle, and please think about motorcycle safety before, during and after every single ride!
